Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Plastic PETG is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions Is Plastic PETG stronger than Plywood? Plastic PETG is stronger: its yield strength is 46.2 MPa against tensile strength 41.4 MPa for Plywood (12%).
Which is stiffer, Plastic PETG or Plywood? Plywood is stiffer: Young's modulus 7.45 GPa against 1.94 GPa for Plastic PETG, so the same part in Plywood deflects less under the same load.
Which conducts heat better, Plastic PETG or Plywood? Plastic PETG conducts heat better: 0.21 W/m·K against 0.12 W/m·K for Plywood.
Which expands less with temperature? Plywood expands less: 3.8 µm/m·K against 51 µm/m·K for Plastic PETG.
